Answer 3 quick questions and we'll point you to the right product.

Question 1 of 3
What is your primary application environment?
Non-Reinforced Inflatable Seals
Extruded profiles in virtually any shape, size, and configuration

Non-reinforced inflatable seals are the most versatile and cost-effective inflatable sealing solution for standard applications. Produced as extrusions bonded into custom shapes, these seals can be made straight, as endless loops, or with molded corners at any angle. Dynamic Rubber can produce virtually any cross-section profile and bond it into any geometry your application requires.

When inflated, the seal expands against a mating surface to create an airtight, watertight, or gas-tight barrier. When deflated, it fully retracts — making it ideal for applications requiring repeated access such as clean room doors, autoclave chambers, and medical sterilizers.

Key Features

  • Straight, endless loop, or molded corner configurations
  • Operating pressures up to 3–5 bar
  • Any cross-section profile available
  • Most cost-effective for standard applications
  • Rapid full retraction when deflated
  • Custom shapes without high tooling costs

Available Materials

  • EPDM — ozone & weather resistance
  • Silicone — wide temperature range
  • Neoprene — good general purpose
  • Nitrile — oil & fuel resistance
  • FKM (Viton) — chemical resistance
  • Butyl — low gas permeability
Fabric Reinforced Inflatable Seals
Fully molded seals for higher pressures and extreme environments

Fabric reinforced inflatable seals are fully molded seals built around the same operating principles as homogeneous inflatable seals, but with internal fabric reinforcement that dramatically increases pressure capacity. The reinforcement layer allows these seals to withstand higher internal pressures, survive heavier loads, and deliver consistent uniform operation over thousands of cycles in demanding environments.

DRI can match any competitor's cross-section profile or engineer a custom reinforced seal from scratch. If your application requires a non-enclosed retainer environment, extreme cycle life, or exposure to aggressive chemicals and temperatures, fabric reinforcement is the right solution.

When to Specify

  • High operating pressures required
  • Extremely heavy loads on seal face
  • High-cycle / long service life applications
  • Non-enclosed retainer environments
  • Replacing a competitor's reinforced profile
  • Extreme chemical or thermal exposure

Reinforcement Fabrics

  • Kevlar — ultra-high strength
  • Nylon — good general reinforcement
  • Fiberglass — heat & chemical resistance
  • Polyester — dimensional stability
  • Dacron — excellent fatigue resistance
  • Cotton — flexibility & conformability
Nuclear Seals
Nuclear inflatable seals for PWR steam generator nozzle isolation

Dynamic Rubber manufactures nuclear inflatable seals for PWR steam generator isolation, reactor coolant system maintenance, and critical outage applications. Our dual-seal design — a wet seal and a dry seal — provides passive fail-safe redundancy that keeps systems isolated without relying on active monitoring.

Engineered to custom bore sizes and manufactured from nuclear-grade elastomers qualified for RCS chemical and radiation environments, our seals enable parallel refueling and steam generator maintenance — saving 5–14 days of critical-path outage time per steam generator.

Applications

  • PWR steam generator & RCS loop isolation
  • RCS maintenance & inspection access
  • Parallel refueling & SG maintenance
  • Pool gate seals & airtight door seals
  • Molded compression gaskets
  • Chemical processing vessel isolation

Key Features

  • Dual wet seal + dry seal redundancy
  • Passive fail-safe — stays sealed if air pressure lost
  • Nuclear-grade elastomers (EPDM, Silicone, Butyl)
  • Custom bore sizes available
  • Saves 5–14 days outage time per S/G
  • Enables parallel refueling & SG maintenance
Inflatable Bladders
Precision bladders for composite molding and industrial tooling

DRI manufactures custom inflatable bladders for composite molding processes and industrial tooling applications. These bladders apply uniform internal pressure inside composite layups during cure cycles, ensuring consistent wall thickness and void-free laminates across complex 3D geometries. Compatible with both autoclave and out-of-autoclave manufacturing processes.

Applications

  • Aerospace structural components
  • Marine hull & deck construction
  • Automotive composite parts
  • Wind turbine blade manufacturing
  • Sporting goods & recreation
  • Industrial pipe fittings

Process Compatibility

  • Autoclave molding
  • Out-of-autoclave (OOA)
  • Resin Transfer Molding (RTM)
  • Vacuum infusion
  • Press molding
  • Complex 3D geometries
Pharmaceutical & Food Grade Seals
FDA-compliant inflatable seals for pharmaceutical, food processing, and sanitary environments

Dynamic Rubber manufactures FDA-compliant inflatable seals for pharmaceutical and food processing applications where hygiene, chemical resistance, and temperature performance are critical. Our seals create airtight perimeters around smokehouse doors, retort vessels, autoclave doors, clean rooms, and processing tanks — preventing contamination while reducing heat loss and improving processing yield.

All compounds are selected to resist steam, smoke, and the harsh cleaning chemicals used in sanitary environments. EPDM and Silicone options are available, along with standard profiles and custom geometries to fit your specific equipment.

Applications

  • Smokehouse doors & retort vessels
  • Autoclave doors & clean rooms
  • Pharmaceutical vessels & lab equipment
  • Bulk bag filling & processing tanks
  • Sanitary processing equipment

Key Features

  • FDA-compliant food-grade elastomers
  • Resists smoke, steam & harsh cleaning chemicals
  • Reduces heat loss & improves processing yield
  • EPDM & Silicone options
  • Standard profiles & custom geometries available
Small & Large Diameter Seals
Precision miniature seals to large-format continuous extrusions — any size, any geometry

DRI manufactures inflatable seals across the full size spectrum. Our precision miniature seals are engineered to the tight dimensional tolerances required by semiconductor process chambers and medical equipment, with low-outgassing compounds available for clean room and vacuum applications. Custom profiles for confined or complex geometries are available.

For large diameter applications, we produce non-reinforced seals via continuous cure extrusions, with long seals available via splicing in both reinforced and non-reinforced configurations. Segmented tooling is available to fully mold any size. Applications range from vacuum and airtight sealing to clamping, lifting, and uniform pressure bonding.

Applications

  • Semiconductor process chambers & medical equipment
  • Vacuum, airtight, watertight & dust control sealing
  • Clamping for holding objects during cutting operations
  • Pressure application for lifting
  • Uniform pressure for bonding applications
  • Small access doors, ports & precision fittings

Key Features

  • Tight dimensional tolerances
  • Low-outgassing compounds available
  • Custom profiles for confined or complex geometries
  • Large diameter via continuous cure extrusions
  • Long seals via splicing — reinforced or non-reinforced
  • Segmented tooling to fully mold any size
